In an increasingly fast-paced lifestyle, sleep is often undervalued, despite its central role in regulating the immune system. The relationship between sleep, cell repair and immune response is now well documented and is recognised as one of the most important elements in maintaining health over time.<\/p>\n

The importance of a good night's rest for cell repair<\/h4>\n

Sleep is not just a break from daily activity. It is a biologically active period during which the body directs resources towards essential repair and regulation processes. During the night's rest, mechanisms involved in cell renewal, memory consolidation, metabolic balance and modulation of the immune response take place.<\/p>\n

These processes depend on the proper organisation of sleep, both in terms of quantity and quality.<\/p>\n

Repair and regeneration during sleep<\/h4>\n

While we sleep, the body's tissues enter phases of cell repair and regeneration. This phenomenon is particularly relevant after the physical and metabolic wear and tear accumulated throughout the day. Chronic sleep deprivation can interfere with these mechanisms, reducing the efficiency of cell repair and making the body more vulnerable to physiological dysfunctions.<\/p>\n

Modulation of the immune system during sleep<\/h4>\n

During sleep, there is a change in the activity profile of the immune system, including an increase in the production and release of certain cytokines, such as interleukin-1, interleukin-6 and tumour necrosis factor. These molecules take part in coordinating both the innate and adaptive immune response.<\/p>\n

When sleep is insufficient or fragmented, the production of these substances can be altered, which tends to compromise the effectiveness of the immune response and the body's ability to adapt to external agents.<\/p>\n

Consequences of sleep deprivation on immune function<\/h4>\n

Chronic sleep deprivation has been associated with significant changes in the functioning of the immune system. Among the effects described are:<\/p>\n
